Dometic Thermostat
« on: December 02, 2016, 08:05:18 pm »
My Dometic Thermostat shows fan,cool,furnace, & heat strip. For some reason I can't get the heat strip (green led) to light up or work. When I rotate it down to heat strip it goes directly on/off . What am I doing wrong? I do what the instructions tell me. Is their a trick to this. Any help is greatly appreciated.
Thanks
Sandy

Sandy, My guess is the your AC unit doesn't have a heat strip in it. You will need to look at your model number and check and see if it came with it,

You might be right. I take it the model number is on the AC unit? Can I see it from inside or climb up to see it.

Sandy, if you remove the filters from the inside and look up into the A/C unit, you  will see four Philips head screws, one on each corner. Remove the two rear ones and peek into the rear of the A/C. You should see a U shaped coil with fins on it. That is the heating element. If you see a heating element you need to call the factory and talk to them. If don't see one,  call them and ask why you don't have one.

Sandy,
I know you are trying to sort out why the heating elements in your AC do not work but we found out in a previous camper a portable electric heater is capable of putting out the same amount of heat as the AC heating coils.  The small portable heaters are typically much quieter and allow you to move the heat to where you need it most.  These are relatively cheap and available from many sources including Walmart.  We have a heat pump instead of AC heating elements in our PC but typically use the portable electric heaters for the reasons mentioned above.  Many of the portable units have a rudimentary thermostat to allow reasonable temperature control.

One of these could get you heat now and allow you to determine why your AC heating coils are not working, then you could determine which method you prefer.

I totally agree.  Heat from below, placed in front of where the cold comes in from worst which is the cab area, does a much better job and so quietly too.

Still, it would be nice to have the roof heater working, assuming you have one.  If you don't have one, I don't think you are missing much at all.  As I recall, our heat strip was optional.  Back in 2007, I think we paid extra for it, but it might have been part of the "Premium Convenience Package" back then.

Hello Sandy,

We use a small space heater as supplemental heat. It's very quiet and does a good job keeping the living area warm.
Last night it was snowing with the outside temp around freezing and it was nice and warm in our 2910.

Solved my problem. Talked with PC this morning. My unit, which I purchased in Oct., was up-graded to a 15K unit. At that time only 13.5K units had heat strips. I'm good with that. A small ceramic heater will be just fine, as others have mentioned. Many thanks for your help and responses.
